I didn’t even have to pause with this one. The Book Thief immediately popped into my mind. The book, published in Australia in 2005 and worldwide in 2006, is one of my favorites. It’s unique because it’s narrated by Death, but it deals with universal themes.
It’s set during World War II and tells the story of a young orphaned girl, her foster family, and their small German town. I think it’s one that will stand the test of time because at this point I’ve seen it presented in so many different ways. Though the book is the absolute best, I’ve now seen it as both a movie and a play as well. I’ve read it, re-read it, listened to the audio version and each time it gets better and I notice something new.
I think the thing that truly makes a classic a "classic" is that it's relevant to new generations and has something new to say to them. There’s no way to know for sure, but I think that in 50 years people will still be discovering this one for the first time and falling in love with the story.
